Here is video of the kids from So You Think You Can Dance performing on last night's Idol Gives Back. They killed it!
From what I can tell (they're moving so fast!), the dancers are Season 1's Nick, Melodie, Jamile and Ashlee; Season 2's Benji, Travis, Dmitry, Donyelle; and Season 3's Lacey, Danny, Pasha, Cedric, Dominic, Hok and Lauren.
Burning question: where was Season 2's Heidi and Season 3's champ Sabra?? Discuss!
